The concept of public trust relates back to the origins of democratic government and its seminal idea that within the public lies the true power and future of a society; therefore, whatever trust citizens place in its officials must be respected. One of the reasons that bribery is regarded as a notorious evil is that it contributes to a culture of political corruption in which public trust is eroded. Other issues related to political corruption or betrayal of public trust are lobbying, special interest groups and the public cartel.
